. IMPEOvEMEET In VAPOR-BURNEBS.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, Samoan B. Horxms andEnwhnn H. Aunnnson,ef'Eastom'in the county of Talbot, and State of .Yl'aryland, haveinvented anew' and improved Vapor-Burner; and we do hereby declare thefol-t lowing to be a full-,clear, and exact description of the some,suflicient to chable those skilled'in the art to which the inventionappertains to fdlly understand and use-it, reference-being had to theaccompanying drawings, forming. part of this specification, in which-Figure 1 is a. top view.-

. Figure 2 is a vertical section through the line a: of fig. 1.

Figure 3 is'a vertical section through the line y of fig. 1. p

This invention is an improvement upon the vapor-burner patented by us,April 3, 1860, and consists in using four holes instead of the two holesand slit of the former burner, and a transverse concaveplate in additionto the concave plate shown in the former invention.

We construct or procure the single-tube fluid-lamps,'of any known form,and insert the ordinary fluid-wick in the tube F of the lamp,.in theusual manner, letting the wick pwjectalittle above the top of the tube.Wethen construct a shor't tube, D, just large enough to fit tightly overthe tube ligand slide upa nd down upon it; To the top of the short tubeD is attached a horizontal plate, B, curved upwards at its ends, and oftheform shown clearly in fig. 1. Another plate extends across the centreof plateB, projecting upwards at its sides, opposite to the burner; or,in lieu of this second plate, the'plate B may be provided with .twoears, 0 0, extending. outward and upward from its sides opposite to theburner, as shown in .figsnl, 2, and 3.

r The burner A is of the ordinary shape, but instead of a slit, withtwo. large holes at its.extremities,'is

provided only with four holes--two-small ones, a a, at the centre of theplate B, where it joins the burner, and

through the instrumentality of the'plate B.

two other smallones, a a, on the sides jot the burner, equidistantbetween the holes on, but considerably higher. The jet that proceedsfrom these side holes a'a impinges against the career, and by heatingthem, serves more eil'ectually to generate gas from the wick. The jetsfrom the lower holes, a a, operate in the same manner,

The great advantage of this improved form of vapor-burner overthathitherto used by us lies in the fact I that its light cannot beextinguished by any sudden gust of wind striking it sideways. Infthe oldburner, the flame, under such circumstances, was liable to be blown ofiof the plate, or. t be blown away f th b p ends of the plate, so thatthey would become cooled, and the gas'would cease to generate in thetube. This improved burner isnot liable to that objection, for if thewind comes upon it in such a manner as to extinguish the jets from a a,the ears 0 e and theburner itself will protect the top jets, and preventthe-light of one or both of them from being blown out.. Theflttln,Wl'lGHl)l0Wll sideways, will'always envelope one of the cars a a,and the heat transmitted through that ar will keep up the temperature ofthe tube below, and prevent any interruption of the generating processwithin the tube. When the gust is over, the vflame from the lighted topjet will relight the end jets, and the other top jet, if it shall havebeen extinguished.-

Ate. suitable distance below the top of the tube D we attach a circularplate or button, E, by which to move the tube D up and down upon thewick-tube F. This button is made in the form shown in fig. 1, and isprovided with a ring, 6, of rubber, wood, or other suitablenon-conducting substance, around its outer edge, to prevent it fromburning the fingers when it is necessary to take hold of it.

The intensity of the light produced is regulated, as in the old lamp,bysliding' the tube D up or down, thereby causing the ,heated burnertoa'pproach or recedefrom the Wick, and thus iucreasibg' or diminishingthe supply of gas.

Having thus described our invention, what we claim as next, and desireto secure by Letters Patent, is-- I The burner above described, havingthe central cone A pierced with four holes, a 0: Ma, at the pointsspooifiefi when us d i combination with aplote, B, bent up at the ends,and hoving ears, 0 c, orojeoting ooovord from its =sdessubstaritially asand for the purposo described.
